BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to compositions, kits and methods for treating hair. More particularly, the present invention includes compositions, kits and methods for treating hair using compounds described below, but without agents for effecting polymerization. The inventive compositions, kits and methods may also be used on hair other than on the scalp. In addition, the inventive compositions, kits and methods may be used on animals other than humans, including on the hair or fur of domesticated animals, including on cats and dogs.

2. Background of the Invention

The hair care industry is a multi-billion dollar industry in the United States alone. The industry includes the development, production, and marketing of a large array of products for hair care, including shampoos, gels, mousses, lotions, sprays, conditioners, coloring products, pomades, serums, waxes, and repair products. Most of these products utilize pre-formed polymers developed to impart a desired characteristic upon application to a user's hair. For example, polymers are used to give hair shine, style hair, preserve hair style, give hair a desired texture or feel, enhance hair color, condition hair, dry hair so it sets quickly, straighten or smoothen hair, soften hair, strengthen hair, make hard-to-treat hair manageable, enhance optical properties, provide hold to hair, provide frizz control and/or to repair damaged hair.

Existing hair care treatments, however, suffer from numerous limitations. One problem common to many hair care products is poor efficacy and longevity. For example, existing hair care treatments are not robust and can lose their efficacy over the course of a day. Many treatments lose their efficacy upon exposure to water or excess humidity. In addition, many hair treatments weigh down hair, flake off, leave unsightly residues, fail to dry and set quickly, do not provide adequate hold, and are not effective for hard-to-treat hair (e.g., naturally curly hair). Treatments have been developed which overcome some of these issues; however, they typically involve permanently treating the hair with reducing and/or oxidizing agents which can damage hair. Thus, there remains a need for hair treatments that withstand the rigors of a typical user's daily routine and can maintain efficacy in a variety of environments without damaging hair fibers. In addition, hair care products which are designed to protect hair or deliver agents which improve hair strength, shine, color, and arrangement suffer from similar limitations as they also exhibit poor efficacy and longevity requiring daily application. It is preferable that a hair treatment be long lasting, not weigh down hair, not flake, and not leave any undesirable residues. Furthermore, the hair treatment should preferably dry and set relatively quickly, provide adequate hold, and be able to manage hard-to-treat hair.

SUMMARY OF THE INVENTION

As described herein, it has been discovered that certain organic chemical compounds, such as small molecules, applied to hair produce effects and characteristics desired by hair product consumers. The compounds are preferably not polymers such as those typically used in hair care products. In certain embodiments, the organic compounds are fluorinated. In certain embodiments, the organic compounds are chlorinated. In certain embodiments, a combination of compounds described herein are used to treat hair. The compositions, kits and methods of the present invention afford numerous beneficial effects that are especially desired for treating hair on the scalp, including: (1) controlling moisture penetration into the hair (frizz control), (2) providing a soft feel to the hair, without a harsh feeling (conditioning), (3) increasing the shine of the hair, (4) enhancing the hair's color, (5) avoiding the feeling of stickiness to the hair (and consequently resisting accumulation of dirt to the hair), (6) dries and sets quickly, (7) can help generate and or preserve the style of the hair, (8) adding strength to the hair, (9) leaving a low amount of residue (are “weightless”), (10) do not flake off the hair, (11) lasting over the course of more than one day, even more than 5 days, (12) affecting, including reducing, the surface energy of the hair (and thereby affording quicker drying of hair), (13) affording manageability for hard-to-treat hair, as well as repairing damaged hair, (14) providing hold, and (15) providing shape.

The present invention provides novel cosmetic hair care compositions for use on hair. The compositions include an active hair care ingredient as described herein and in U.S. patent application, U.S. Ser. No. 11/734,425, filed Apr. 12, 2007, which is incorporated herein by reference for the monomers recited therein, and a cosmetically acceptable excipient. Cosmetically acceptable excipients include preservatives, antioxidants, chelating agents, sunscreen agents, vitamins, dyes, hair coloring agents, proteins, amino acids, plant extracts, humectants, fragrances, perfumes, oils, emollients, lubricants, butters, penetrants, thickeners, viscosity modifiers, polymers, resins, hair fixatives, film formers, surfactants, detergents, emulsifiers, opacifying agents, volatiles, propellants, liquid vehicles, carriers, carriers, salts, pH adjusting agents, neutralizing agents, buffers, hair conditioning agents, anti-static agents, anti-frizz agents, anti-dandruff agents, hair waving agents, hair straightening agents, relaxers, absorbents, and combinations thereof. Examples and appropriate amounts of each of these categories of cosmetically acceptable excipients is described herein. In certain embodiments, the cosmetic hair care compositions include at least two or more cosmetically acceptable excipients. In certain embodiments, the cosmetic hair care composition simply includes the active hair care ingredient and a cosmetically acceptable excipient that is volatile, leaving only the active ingredient on the subject's hair. The inventive hair care compositions include shampoos, conditioners, mousses, gels, hair sprays, creams, pomades, serums, waxes, coloring compositions, styling compositions, repair compositions, etc.

The following are more general terms used throughout the present application:

As used herein, the singular forms “a”, “an”, and “the” include the plural reference unless the context clearly indicates otherwise. Thus, for example, a reference to “a monomer” includes a plurality of such monomers.

“Animal”: The term animal, as used herein, refers to humans as well as non-human animals, including, for example, mammals, birds, reptiles, amphibians, and fish. Preferably, the non-human animal is a mammal (e.g., a rodent, a mouse, a rat, a rabbit, a monkey, a dog, a cat, a primate, or a pig). An animal may be a domesticated animal. In certain embodiments, the animal is human. An animal may be a transgenic animal

“Biocompatible”: The term “biocompatible”, as used herein is intended to describe compounds that are not toxic to cells. Compounds are “biocompatible” if their addition to cells in vitro results in less than or equal to 20% cell death. The administration in vivo does not cause inflammation, cancer, birth defects, neurotoxicity, or other such adverse side effects.

“Biodegradable”: As used herein, “biodegradable” compounds are those that, when introduced into cells, are broken down by the cellular machinery or by hydrolysis into components that the cells can either reuse or dispose of without significant toxic effect on the cells (i.e., fewer than about 20% of the cells are killed when the components are added to cells in vitro). The components preferably does not cause inflammation, cancer, birth defects, neurotoxicity, or other such adverse side effects in vivo. In certain preferred embodiments, the chemical reactions relied upon to break down the biodegradable compounds are uncatalyzed. For example, the inventive materials may be broken down in part by the hydrolysis of the ester bonds found in cross-linked material.

Active Hair Care Ingredients

A variety of active hair care ingredients may be used in the inventive cosmetic hair care compositions. A variety of chemical compounds may be used in accordance with the present invention to treat hair. In certain embodiments, the compounds are small molecules. In certain particular embodiments, the compounds are small organic molecules. In certain particular embodiments, the compounds are fluorinated, small organic molecules. In certain particular embodiments, the compounds are non-fluorinated, small organic molecules. In certain particular embodiments, the compounds are chlorinated, small organic molecules. Combinations of compounds may be used to treat hair, thereby creating different cosmetic effects. The availability of a wide range of compounds also allows for treating hair to achieve various desired properties, including: (1) controlling moisture penetration into the hair (frizz control), (2) providing a soft feel to the hair, without a harsh feeling (conditioning), (3) increasing the shine of the hair, (4) enhancing the hair's color, (5) avoiding the feeling of stickiness to the hair (and consequently resisting accumulation of dirt to the hair), (6) dries and sets quickly, (7) can help generate and or preserve the style of the hair, (8) adding strength to the hair, (9) leaving a low amount of residue (are “weightless”), (10) do not flake off the hair, (11) lasting over the course of more than one day, even more than 5 days, (12) affecting, including reducing, the surface energy of the hair (and thereby affording quicker drying of hair), (13) affording manageability for hard-to-treat hair, as well as repairing damaged hair, (14) providing hold, and (15) providing shape.

Some of the above-identified beneficial attributes have been afforded in existing hair care products through use of compositions containing conditioning agents such as silicones or other polymers, which have a high affinity for keratin and especially for the hair on the scalp. Such compounds include, but are not limited to silicones such as cyclomethicone, dimethiconol, dimethicone, cyclopentasiloxane, cyclomethicone, trimethylsiloxyphenyl, dimethiconol, cyclopentasiloxane dimethicone copolyol. However, the coating on keratin fibers, such as the hair, obtained with such compositions often has an unpleasant tacky feel and also may be readily lost via transfer, for example when a hand is passed through the hair. In addition, as a result of such transfer the hair may give the impression of being dirty, sticky or tacky. Also, the effects of the use of such silicone compounds and polymers is not long lasting as they are removed by shampooing the hair, thus making it necessary to repeat application of the compositions to the hair, for example, after rinsing, washing or shampooing. Moreover, residue from silicone compounds may build up on the hair and contribute to making the hair limp, contribute to worsening frizz and when used with heat appliances silicone containing compositions may cause “silicone burn.”

The inventive compositions and methods therefore afford the benefits of silicone containing composition without many of their drawbacks. Accordingly, the compositions, methods of the invention preferably do not employ a compound containing a silicone compound; preferably the compositions, methods employ less than 10% wt/vol of such a silicone compound, preferably less than 1% wt/vol of such a silicone compound, more preferably below 0.5% wt/vol, more preferably below 0.2% wt/vol; more preferably below 0.1% wt/vol; more preferably below 0.05% wt/vol; more preferably below 0.01% wt/vol; and still more preferably below 0.001% wt/vol.

Attempts have been made to treat hair with certain acrylate monomers and polymerize them in situ by free-radical polymerization. For example, U.S. Pat. No. 3,676,550 discloses use of certain acrylate and methacrylate compositions as hair treatments. The acrylate and methacrylate monomers employed in U.S. Pat. No. 3,676,550 do not readily polymerize in the presence of moisture. Indeed, those compositions employ an “inert solvent” (which contain 10 to 90% water; the remainder being water-miscible organic solvent).

Unfortunately, compositions and methods that employ in situ free radical polymerization tend to degrade the hair, probably since harsh chemicals are involved. Another problem reported for such compositions and methods is that the chemicals employed irritate and/or are harmful to the hair and/or skin and leave the hair feeling harsh, as well as causing hair discoloration. Furthermore, many such hair treatments may involve reduction of hair prior to treatment, which causes additional hair damage.

In contrast, the compounds employed in the inventive compositions and methods are not toxic, are not harmful to the hair or skin and do not leave the hair feeling harsh or cause hair discoloration. Moreover, the inventive compositions and methods do not rely on free-radical polymerization agents or pre- or post-treatment of the hair with either a reducing or oxidizing agent. In certain embodiments, the inventive compositions and methods do not employ a free radical initiator, a polymerization initiator or a polymerization catalyst. In certain embodiments, the inventive compositions and methods do not employ more than about 0.001% weight/weight, more preferably not more than about 0.01% weight/weight, even more preferably not more than about 0.1% weight/weight of a free radical initiator, a polymerization initiator or a polymerization catalyst. In certain embodiments, there is not more than approximately 0.001 per mol of a free radical initiator, a polymerization initiator or a polymerization catalyst per mol of monomer. Accordingly, the inventive compositions and methods preferably do not employ more than about 0.001% weight/weight, more preferably not more than about 0.01% weight/weight, even more preferably not more than about 0.1% weight/weight of a peroxide; a peracid, a peroxide generating system; a peroxomonosulfate; a peroxodisulfate; a diazo compound, a redox catalyst (such as NH₄S₂O₈/NaHSO₃; H₂O/Fe³⁺; S₂O₈ ⁻²/RSH; Fe³⁺/HSO₃ ⁻; Ce⁺⁴/ROH; KMnO₄/citric acid; sodium sulfite).

One approach to avoid the harsh chemicals and/or conditions involved in in situ polymerization has been to avoid monomers that do not require such initiators, but rather employ monomers that readily polymerize in the presence of moisture (water). Accordingly, U.S. Pat. No. 5,082,010 shows that cyanoacrylates have been used as a treatment for hair. Cyanoacrylate monomers readily polymerize in the presence of moisture and are said to be “instant adhesives.” “Crazy Glue” (2-cyano acrylate) is such an example. In addition, a medical glue, 2-octyl cyanoacrylate, is FDA approved for use as a wound adhesive for use in surgery. Contact with the moisture in the air, or from a biological fluid or tissue, is sufficient for polymerization of such cyanoacrylates.

In contrast, compositions of the present invention employ monomers that do not readily polymerize simply by exposing the monomer to moisture, such as by contact of the monomer with moisture from a biological fluid or tissue as for cyanoacrylates. Indeed, the monomers of the present invention may be formulated as stable compositions using aqueous carriers, for example containing greater than 90% water as carrier. The monomers of the present inventions are not cyanoacrylates.

Use of the inventive compositions are simple and easy. Preferably, the inventive composition is applied to hair that has been just washed. It is not necessary to completely dry the hair, but rather, the hair may be towel dried, allowing for the hair to remain moist, or even dripping wet. A composition of the invention is applied and worked into the hair for example, by the use of a comb or brush, after which the hair is blow dried, preferably using heat from a conventional hair drier, even more preferably, using a heat source below 160° C. and even more preferably, using a heat source below 120° C. In the case of a composition that is a cream, it is recommended that the cream be worked into the ends of the hair, after which the composition is worked into the remaining length of the hair. It is not necessary, and indeed it is preferable, that there be no rinsing step after application of the inventive composition to the hair.

In certain embodiments, two different compounds are applied to hair. In other embodiments, three different compounds are applied to hair. When different compounds are used, the compounds are applied to hair simultaneously or separately. In certain embodiments, the compounds are all in the same solution which is applied to the hair. In certain embodiments, one of the compounds is fluorinated, and another is not fluorinated. In other embodiments, all compounds are fluorinated.

The compounds described herein can be applied to hair using any method known in the art. The hair to be treated is brushed, sprayed, rubbed, dipped, soaked, etc. with the compound or a solution of the compound. In certain embodiments, the compound is dissolved in a carrier such as water, alcohol, water/alcohol or alcohol/water mixtures (between 5%/95% to 10%/90%, between 10%/90% to 20%/80%, between 20%/80% to 30%/70%, between 30%/70% to 40%/60%, and between 40%/60% to 50%/50%) or other carriers and applied to hair.

Polymerization Initiators

Polymerization is typically effected through use of a polymerization initiator. A polymerization initiator may be chosen based on the type of monomers being used, the type of initiation (e.g., heat or photoinitiation), and solubility of initiator in a carrier or other excipient. Preferably the present invention does not include a polymerization initiator, more preferably it does not include a polymerization initiator that is activated under ambient or uv light or using a heat source below 160° C., and even more preferably using a heat source below 120° C.

The present invention preferably does not include a free radical initiator, which forms free radicals upon exposure to light or upon heating. Typically, the initiator decomposes upon heating or exposure to a certain wavelength of light to yield two free radicals that initiate the polymerization reaction. The free radical generated from the initiator reacts with an unsaturated functional group (e.g., an alkene, acrylate, or methacrylate functionality) of a monomer thus beginning the chain reaction which results in the formation of the desired fluorinated polymer.

The present invention preferably does not include oxygen tolerant polymerization initiators. Oxygen-tolerant initiators eliminate the need for an oxygen-free or an oxygen-reduced environment for the polymerization reaction to take place. Such oxygen-tolerant initiators allow for the polymerization reaction to take place directly on hair fibers in a normal atmosphere with about 21% oxygen. Exemplary oxygen tolerant polymerization initiators include 4,4′-azobis(4-cyanovaleric acid); 1,1′-azobis(cyclohexanecarbonitrile); 2,2′-azobis(2-methylpropionitrile); 2,2′-azo-bis-isobutyronitrile (AIBN); benzoyl peroxide; 2,2-bis(tert-butylperoxy)butane; 2,5-bis(tert-butylperoxy)-2,5-dimethylhexane; bis[1-(tert-butylperoxy)-1-methyl ethyl]benzene; tert-butyl hydroperoxide; tert-butyl peracetate; tert-butyl peroxide; tert-butyl peroxybenzoate; cumene hydroperoxide; dicumyl peroxide; lauroyl peroxide; peracetic acid; potassium persulfate; 2-hydroxy-2-methyl-phenylpropanone; 2,4,6-trimethylbenzoyldiphenyl phosphine oxide; 2,4,6-trimethyl benzophenone; oligo(2-hydroxy-2-methyl-1-(4-(1-methylvinyl)phenyl)propanone; and 4-methylbenzophenone.

The present invention preferably does not include an initiator. To effect polymerization typically, the concentration of initiator is approximately 1000-fold, 100-fold, 10-fold, or 5-fold less than the concentration of monomer. To effect polymerization in some cases the initiator is at a concentration of more than about 0.001%. In other cases the initiator is at a concentration of more than about 0.01%. In certain other cases the concentration of initiator is more than about 0.1%. Practice of the present invention preferably avoids employing any of the above mentioned ratios of initiator to monomer and/or avoids employing any of the stated initiator concentrations.

The present invention preferably does not include an initiator that is a free radical thermal initiator. A thermal initiator is designed to work at a temperature ranging from 30° C. to 120° C. The present invention preferably does not include a co-initiator. Co-initiators act to lower the decomposition temperature of the initiator. Exemplary co-initiators include, but are not limited to, aromatic amine (e.g., dimethyl aniline), organic peroxides, decahydroacridine 1,8-dione, etc. Other co-initiators are listed below. The heat may be applied to hair with monomer and initiator applied for about 10 seconds to about 5 minutes. The heat source for initiating polymerization may include, but is not limited, to blow dryers, curling irons, hot curlers, hair irons, hair straighteners, hair crimpers, hot air brushes, and hair dryers.

The present invention preferably does not include thermal initiators, such as, azo compounds, peroxides, peracids, peracetates, persulfates, etc. Exemplary thermal initiators include tert-amyl peroxybenzoate; 4,4′-azobis(4-cyanovaleric acid); 1,1′-azobis(cyclohexanecarbonitrile); 2,2′-azobis(2-methylpropionitrile); benzoyl peroxide; 2,2′-azo-bis-isobutyronitrile (AIBN); benzoyl peroxide; 2,2-bis(tert-butylperoxy)butane; 1,1-bis(tert-butylperoxy)cyclohexane; 2,5-bis(tert-butylperoxy)-2,5-dimethylhexane; 2,5-bis(tert-butylperoxy)-2,5-dimethyl-3-hexyne; bis [1-(tert-butylperoxy)-1-methylethyl]benzene; 1,1-bis(tert-butylperoxy)-3,3,5-trimethylcyclohexane; tert-butyl hydroperoxide; tert-butyl peracetate; tert-butyl peracetic acid; tert-butyl peroxide; tert-butyl peroxybenzoate; tert-butylperoxy isopropyl carbonate; cumene hydroperoxide; cyclohexanone peroxide; dicumyl peroxide; lauroyl peroxide; 2,4-pentanedione peroxide; peracetic acid; and potassium persulfate. Many of the above listed thermal initiators are available from commercial sources such as Sigma-Aldrich. The present invention preferably does not include initiators, such as, 2,2′-azo-bis-isobutyronitrile (AIBN) or benzoyl peroxide (also known as dibenzoyl peroxide). The present invention preferably does not include a combination of thermal initiators or a combination of ammonium persulfate (APS) and N,N,N′,N′-tetramethylethylenediamine (TEMED).

The present invention preferably does not include a free radical initiator that is a photoinitiator.

Moisture Resistance

Moisture on hair and its penetration into the hair can disturb the arrangement of hair proteins, resulting in cosmetically undesired changes, such as, an increase of frizz. The present invention provides hair, in particular hair on or from the scalp, with beneficial moisture resistance properties. Moisture resistance in the present invention refers to the hysteresis of water sorption/desorption when measured by Dynamic Vapor Sorption (DVS). In DVS a sample is placed on a microbalance exposed to a continuous flow of air with predetermined and constant relative humidity. As the humid air passes over the sample, a zone of constant moisture concentration is created around it. This zone allows the rapid establishment of water vapor sorption or desorption equilibrium by maximizing mass transport of water vapor into and out of the sample.

Mass changes in the sample (e.g., a swatch of hair) due to water vapor sorption/desorption can be measured between different levels of relative humidity at a particular temperature. The change in mass can be plotted as a function of the relative humidity, which provides information about the nature of water vapor sorption phase (absorption and/or adsorption) when humidity is increased, or, conversely, the nature of desorption of water, when humidity is decreased. The difference in changes in mass at any particular value for relative humidity in the sorption and desorption phases is known as the hysteresis and can be used as a measure to evaluate the ability of a hair treatment to resist or control moisture on and in hair. As described below, the invention affords reduced hysteresis especially over relative humidity values range of 30-80% RH.

In the context of the present invention, moisture resistance is measured according to DVS Protocol I.

DVS Protocol I

1. 1.50 g of bleached hair tress is dampened with 0.30 mL de-ionized water, optionally via pipet, and lightly combed through to remove any tangles. 2. Apply composition to the hair tress according to the following amounts: for a serum (0.10 g to 0.12 g), for a cream/lotion/mousse (0.20 g to 0.25 g), and for a spray (0.35 g to 0.40 g) and is distributed evenly and combed through the hair. Preferably the weight ratio of formulation to hair should be approximately 0.073 for serums, 0.15 for a cream/lotion/mousse and 0.25 for a spray. 3. Styling consists of 10 passes with a hair brush and blow drier set to high, approximately 50-120° C. 4. After styling, the hair is cut and sections from the middle of each tress (approximately 300 mg) are analyzed via DVS. 5. DVS conditions are as follows. Unless otherwise stated the temperature employed is 25° C. Sorption phase: Start at 30% RH and increase up to 90% RH, each step increasing RH by 10%. Desorption phase: Start at 90% RH and decrease down to 0% RH, each step decreasing RH by 10%. At each RH condition, the sample is maintained for 4 hours, and the step up or down to the next RH level is programmed to occur over 20 min period.

Monitoring the hysteresis values from such a DVS experiment on hair samples allows assessment of the ability of a hair treatment to resist or control moisture.

The present invention affords superior moisture resistance compared to either (1) a control treatment using water and (2) a leading silicone product, as Kerastase Olexo Relax Serum®, which in fact increased the hysteresis compared to water. Preferably, use of the invention on a hair tress as described above affords a 4% reduction in the average hysteresis values compared to control (water-treated) hair over the relative humidity range of 30-80% when examined by the DVS protocol described above. More preferably, use of the invention on a hair tress as described above affords more than a 10% reduction and still more preferably more than a 20% reduction, in the average hysteresis values compared to control (water treated) hair over the relative humidity range of 30-80% when examined by the DVS protocol described above. Even more preferably, the invention affords a 50% or more, or even an 80% or more, reduction in the average hysteresis values compared to control (water-treated) hair over the relative humidity values range of 30-80% RH when determined by the DVS protocol described above.

Weightlessness

Those who use hair care products desire the beneficial effects described above. However, such users do not want the feeling of residue/product in or on their hair. A composition that maintains performance, but which does so with less residual weight or “feel” in the hair is, therefore, preferred.

The compositions of the present invention, while maintaining product performance, beneficially lose no less than 25% of their weight, preferably 50% of their weight, more preferably no less than 70% of their weight, still more preferably no less than 80% weight, and still more preferably no less than 90%, and most preferably 95% or higher of their weight after heating at 55° C. and 25% RH for 20 minutes (for spray formulations) and 30 minutes (cream/lotion/serum/mousse) formulations according to the “Weightlessness Test I.”

Weightless Test I

Composition is dispensed into an uncovered container and spread out evenly. For instance, the container is a round container with a diameter of 9 cm and a lip measuring 0.5 cm.

1. The containers are labeled and then weighed immediately before and after dosing with 3 g of formulation. 2. Compositions are left to equilibrate at ambient conditions (25° C., 30% RH) for 5 minutes before placing into the oven. 3. The container is placed into an oven controlled at 55° C. and 25% RH. 4. Each dish is removed and its mass recorded at 20 minutes for spray compositions and 30 minutes for cream/lotion/serum/mousse compositions.

The compositions for treating hair according to the invention on average leave at least 25% less residue upon dry-down when following package instructions for amounts used for Kerastase Oleo Relax Serum®, John Frieda Frizz Ease®, Biosilk Silk Therapy®, Redken Smooth Down Heat Glide®, Nexxus Sleek Memory Straightening Smooth Spray®, Barex Re-define Crème®, Fekkai Glossing Cream® and Bedhead Curls Rock®. It is believed that one reason for the “weightlessness” benefits of the inventive formulations is that they do not require, and preferably do not include, silicone compounds at levels found in the above identified hair care products.

Dirt Resistance

Many materials are used to control or reduce moisture penetration into hair fibers. However, the majority of these materials are oil-based or silicone-based. The resulting effect is modest moisture resistance combined with a heavy residue feel which attracts grease and particulates. It is desirable in the art to create a composition that will control or reduce moisture penetration into hair fibers while leaving the hair feeling lightweight, non-greasy, and minimizing attraction of dirt/particulates.

The attraction of dirt and particles to the hair leaves the hair limper, heavier, and duller throughout the day. The ability to resist environmental pollutants gives the hair longer lasting style and shine. Accordingly, the ability of the present inventive hair care compositions to resist dirt accumulation was examined and compared to Kerastase Oleo Relax Serum®. Corn starch was selected as simulated dirt. USP corn starch is uniformly-white and can associate with hair, providing excellent contrast on black hair, thereby allowing for a quantifiable Gray-scale measurement via digital photography. Remaining corn starch was also assayed by gravimetric analysis.

Starch Resistance (Gravimetric)

The inventive hair care compositions when tested on hair as described below should afford gain in weight of no more than 15% by weight, preferably no more than 10% by weight, more preferably no more than 7% weight, and most preferably no more than 5% by weight when subjected to the Starch Test I.

Starch Test I

1. 1.50 g of virgin dark brown hair tress is dampened with 0.30 mL of water. 2. Apply composition to the hair tress according to the following amounts: for a serum (0.10 g to 0.12 g), for a cream/lotion/mousse (0.20 g to 0.25 g), and for a spray (0.35 g to 0.40 g) and is distributed evenly and combed through the hair. Preferably the weight ratio of formulation to hair should be approximately 0.073 for serums, 0.15 for a cream/lotion/mousse and 0.25 for a spray. 3. The hair was styled with a hair brush and blow drier on high speed and high temperature, approximately at 50-120° C. for 30 seconds. 4. The tress is saturated in a bath of corn starch, for instance, in about 2 grams of corn starch, USP. 5. The tress is removed from the corn starch bath and shaken by hand until all loose corn starch is removed, for instance, for 10 seconds. 6. The tress is weighed and the new mass is recorded.

Starch Resistance (Gray Value)

The inventive hair care compositions when tested on hair as described below should display equal Gray values to those generated by a similar sample treated with water, preferably the composition-treated hair sample should display Gray values 5% less than those generated from a similar sample treated with water, more preferably the composition-treated hair sample should display Gray values 10% less than those generated from a similar sample treated with water, and most preferably the composition-treated hair sample should display Gray values of at least 15% less than those generated from a similar sample treated with water when subjected to Starch Test II.

Starch Test II

1. 1.50 g of virgin dark brown hair tress is dampened with 0.30 mL of water. 2. Apply composition to the hair tress according to the following amounts: for a serum (0.10 g to 0.12 g), for a cream/lotion/mousse (0.20 g to 0.25 g), and for a spray (0.35 g to 0.40 g) and is distributed evenly and combed through the hair. Preferably the weight ratio of formulation to hair should be approximately 0.073 for serums, 0.15 for a cream/lotion/mousse and 0.25 for a spray 3. The hair was styled with a round brush and blow drier on high speed and high temperature, approximately 50-120° C. for 30 seconds. 4. The tress is saturated in a bath of corn starch, for instance, in about 2 grams of corn starch, USP. 5. The tress is removed from the corn starch bath and shaken by hand until all loose corn starch is removed, for instance, for 10 seconds. 6. Samples were taped hanging against a black background 7. Photographs were taken from a distance that allowed the entirety of the tresses to be captured, approximately 3 feet away. 8. Images were analyzed using Image J software (Wayne Rasband, National Institutes of Health, USA). Photographs were converted to Grayscale and a box was drawn wide enough to encompass all tresses. The box height was adjusted so as to include only the middle third of the tresses, and the “Plot Profile” feature was used to collect gray value data, which was imported into Microsoft Excel.

The present invention may be used on any animal with hair. The system is particularly useful for treating human hair. However, the hair or fur of other mammals may also be treated. For example, the hair or fur of domesticated animals such as dogs and cats may be treated using the inventive system. In addition, the hair or fur of test animals such as rodents (e.g., mouse, rat, rabbit, guinea pig, etc.) or primates may also be treated. In certain embodiments, hair samples from a human (e.g., hair clippings) or other animals are tested with the present invention. Hair or fur samples treated with the present invention are considered to be within the scope of the invention. These hair or fur samples comprise compound on the hair or fur. In certain embodiments, the hair is human hair. In other embodiments, the hair is non-human hair. In certain embodiments, the hair or fur is dog or cat hair or fur. In other embodiments, the hair is rat, mouse, guinea pig, rabbit, gerbil, or primate hair. The hair treatment system of the present invention can also be used to treat hair contained in wigs, toupees, and hairpieces.

These and other aspects of the present invention will be further appreciated upon consideration of the following Examples, which are intended to illustrate certain particular embodiments of the invention but are not intended to limit its scope, as defined by the claims.

EXAMPLES Example 1 Testing of Treated Hair

Tests as described herein may be used to test shine/luster, break strength, and hair fiber thickness.

In this example, the measure of the hair's shine/luster is proposed. After applying a composition and curling and brushing a hair sample, the hair would be wound around a cylinder and placed under a lamp that mimics sunlight. The width of the cone of luster will be measure and compared with that of a commercial product.

In this example, the measure of the hair's break strength is proposed. Single hair fibers (treated and untreated) can be attached to an Instron which will pull at one end of the fiber, breaking the fiber at a certain force.

In this example, the measure of the hair fiber thickness is proposed. Cross sections of hair fibers (treated and untreated) can be examined and measured by microscopy.

In this example, the humidity resistance of the treated hair is proposed. This property can be measured by placing the styled hair tress in an atmosphere of high humidity.

In this example, the feel is proposed. The parameters of feel can be assessed for a given material on the hair fiber. Several parameters such as tack, slip, stiffness, smoothness, grease, and strength can be evaluated by a blind test of experts.
